Field management techniques of turquoise planting

Turquoise is a biennial plant of the cruciferous family, also known as kale. Due to the sweet taste, fresh and tender meat, crisp and delicate, coupled with its rich nutrients, so the sales in the market is also very good. Because of this, turquoise is widely planted in all parts of our country. in order to ensure the output and quality of turquoise, the editor specially brings you the field management technology of turquoise planting today. Let's take a look.

1. Fertilization

Azure blue has a large demand for nutrients, and it is a kind of fertilizer-loving plant, but when we apply fertilizer, we also need to do it scientifically according to the fertilizer characteristics, growth and planting season of the plant. In addition to the base fertilizer, we also need to give it topdressing in different growth periods, in fertilization or mainly nitrogen fertilizer, the appropriate use of phosphorus and potassium fertilizer. In the growth period of turquoise blue, nitrogen fertilizer is generally used for acupoint application, or irrigation is carried out with fecal and urine water, which can enter an appropriate amount of urea in fecal and urine water. When the blue ball is formed, we need to supplement the phosphate and potassium fertilizer properly to enhance the resistance of the plant and avoid the plant aging. Finally, in the process of ball formation, we also need to supplement calcium, magnesium, zinc and other trace element fertilizer.

2. Watering

The growth of turquoise requires a lot of water, so we need to water many times in the process of planting. After the turquoise blue is planted, it should be watered in time and thoroughly, and then it will be watered again three days later without rain. It is a week later that the watering should be carried out reasonably according to the wetness of the soil. It should not be too wet, but it should also be wet through. Then, if the fertilizer is applied dry every time, we'd better water it after fertilization. There is to wait until the blue ball time, the water demand during this period is very large, at least three or four times to water, replenish water, so that the growth of blue blue will be more fresh and crisp. Finally, I would like to remind you that the phenomenon of stagnant water in the field should not occur. If so, drainage should be carried out immediately.

3. Weeding

In the process of growing turquoise, we also need to weed the turquoise, usually by ploughing. This can not only clean up the weeds in the field, but also enhance the soil permeability, improve the nutrient absorption rate, and promote the growth of plants. In the whole growth process of turquoise blue, it usually needs to be carried out two or three times, but it has to be done before closing the forest. If there are any weeds after closing the forest, the weeds can only be pulled manually.

4. Prevent diseases and insect pests

We also need to pay attention to the prevention and control of diseases and insect pests in the process of planting. Among them, the most important diseases are virus disease, black rot and soft rot, so the first thing we should do is to disinfect the soil in the field with lime water before planting turquoise, and the second is to pay attention to the planting density, which should not be too large. finally, Bordeaux solution and chlorothalonil are used for control. The most harmful pests are aphids, cabbage insects, Plutella xylostella and so on, so we had better use low-toxic pyrethroid insecticides to control them, but we should pay attention to how they can not be sprayed half a month before harvest.

In fact, turnip blue is no different from cabbage in planting technology, and many of them are similar to cabbage cultivation, so it is very simple to grow them. I believe that through the reading of the above, it will be basically clear.
